Hi Josh,
today we managed to make UHD sink and source work in parallel on E100
using FPGA5.bin
by building UHD like this:
git clone git://code.ettus.com/ettus/uhd.git
cd uhd
git pull git://code.ettus.com/ettus/uhd.git next
cd host/
$ mkdir build
$ cd build
$ cmake

we don't manage wih the E100 FPGA5 bitstream.
It is placed in the images directory and we use a new branch but we
don't really think the FPGA5 is used.
What do you mean?
And we still have the same problem with parallel UHD devices (sink/source).
Another guy confirmed it was working for

Hi all,
we are new with E100.
we managed to use UHD:USRP_Source without further configuration and display
it on QT_GUI_SINK.
we don't manage with UHD:USRP_Sink without further configuration:
File /usr/local/lib/python2.6/site-packages/gnuradio/uhd/uhd_swig.py, line
1854, in usrp_sink

OK, first simple reason discovered.
UHD can only be used for one device - either UHD_usrp_sink or source.
How can UHD be used for both devices in parallel?
You have to access both source and sink from the same process, but

Hi Jason,
thanks but I am a little confused.
I would say it is in the same process since I have sink and source in the same
GRC setup. The failure shows up when the generated python script instantiates an
UHD devices the second time as far as I
